A drain pan 20 having a drain hole 22 formed therein to collect and discharge condensed water flowing down the surface of the heat exchanger 15, and disposed below the drain pan 20, through the drain hole 22. The condensate discharged through the drip hole (17a) formed on one side and the water tank 17 is stored and integrally formed in the lower side of the drain pan 20, the portion and the compressor 16 is housed in the compressor (16) ) Is configured to include a barrier (21) partitioned into a portion where it is installed.

An air filter 7 for filtering foreign substances in the air sucked into the cabinet 4 is attached to the suction port 6 of the cabinet 4 and a driving control unit for operating the dehumidifier And a front panel 9 provided with a driving display portion 9b for informing the outside of various operating states of the dehumidifier.

The refrigerant is circulated along the compressor 16, the condenser 14, the expansion valve (not shown) and the evaporator 13 while the compressor 16 and the blowing fan 12 are operated The indoor air passes through the evaporator 13 and the condenser 14.

At this time, condensed water is formed on the surface of the evaporator 13, and the condensed water flows down along the surface of the evaporator 13 and downwardly. The condensed water collects in the drain pan 20, passes through the drain hole 22, Lt; / RTI >

As described above, when the condensed water collects in the water tank 17, the user can remove the condensed water by removing the water tank 17.

However, when the dehumidifier according to the prior art is not used for a predetermined time, dust or the like adheres to the condensed water formed on the surface of the evaporator 13, and there is a problem that an odor occurs due to the condensed water. As such, the smell and dust of the evaporator 13 are directly provided to the user as the blowing fan 12 rotates when the user operates the dehumidifier, so that the user may feel uncomfortable.

The present invention has been made in order to solve the above problems, it provides a dehumidifier control method that improves the convenience of use because the odor generated from the evaporator or dust attached to the evaporator is not supplied to the user due to not using the dehumidifier for a long time. Its purpose is to.

Dehumidifier control method of the present invention for achieving the above object, the first determination step of determining whether the dehumidifier stop time is a predetermined time or more, and if the stop time is a predetermined time or more, the compressor operates, the blowing fan to stop the smell The removal step is included.

In the deodorization step, the compressor is operated so that the evaporator is below the dew point temperature, and the dew point temperature is calculated by extracting from a microcomputer using the temperature and humidity values of the indoor air, or the dew point temperature is the temperature and humidity of the indoor air. Extracting from a pre-computed database using a value, the odor removal step can be maintained for a predetermined time after the evaporator reaches the dew point temperature.

According to the dehumidifier control method of the present invention as described above, the following effects can be obtained.

A first determination step of determining whether the dehumidifier stop time is longer than a predetermined time and an odor removal step of operating the compressor and stopping the blower fan if the stop time is longer than a predetermined time. Odor generated from the evaporator or dust attached to the evaporator is not supplied to the user to improve the convenience of use.

In the deodorization step, the compressor is operated so that the evaporator is below the dew point temperature, and the dew point temperature is calculated by extracting from a microcomputer using the temperature and humidity values of the indoor air, or the dew point temperature is the temperature and humidity of the indoor air. Extracting from a database calculated in advance using a value, the odor removal step can be maintained for a predetermined time after the evaporator reaches the dew point temperature, it can effectively remove the odor and dust.

FIG. 1 is a perspective view of a conventional dehumidifier. FIG.
2 is a flowchart of a dehumidifier control method according to a preferred embodiment of the present invention.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

For reference, the same components as those of the conventional art will be described with reference to the above-described prior art, and a detailed description thereof will be omitted.

As shown in Figure 2, the control method of the dehumidifier of the present embodiment, the first determination step (S5) for determining whether the dehumidifier stop time is a predetermined time or more, and if the stop time is a predetermined time or more, the compressor is operated, the blowing fan The odor removing step (S11) comprises.

When the power of the dehumidifier is turned on by the user or by automatic control of a controller (not shown) (S1), the time when the power of the dehumidifier is turned off is measured (S5).

Next, a first determination step S5 of determining whether the dehumidifier stop time (OFF time) is longer than a predetermined time is continued.

As in the present embodiment, when the power of the dehumidifier is turned on, the first determination step S5 may be executed, but the first determination step S5 may be executed at a predetermined time.

If the stop time is less than a predetermined time, the operation in the normal mode operated by the user.

Subsequently, if the stop time is longer than a predetermined time, the temperature and humidity of the indoor air are measured to obtain a value.

Next, the dew point temperature is calculated by using a microcomputer using the temperature and humidity values of the indoor air, or extracted from a database calculated in advance using the temperature and humidity values of the indoor air to calculate the dew point temperature.

The compressor is operated, followed by an odor removing step S11 for stopping the blower fan.

By not operating the blower in this way, the evaporator can be brought to a low temperature in a short time, and contaminated air is not discharged into the room.

A second determination step S12 of determining whether the evaporator has reached the dew point temperature is followed.

When the evaporator reaches the dew point temperature, the compressor operation time is accumulated (S15).

It is determined whether the accumulated compressor operation time has passed a predetermined time (S17).

The predetermined time may be set to a time at which odors and dust can be effectively removed by an experiment or the like.

In this way, the compressor is operated so that the evaporator is below the dew point temperature, and the odor removing step is maintained for a predetermined time after the evaporator reaches the dew point temperature, thereby effectively removing odors and dust.

If the accumulated compressor operation time has elapsed, the compressor operation is stopped.

Operate in the normal mode operated by the user (S21).

As such, when the dehumidifier is not used for a certain time, the compressor may be operated while the blower fan is not operated to remove dust attached to the evaporator and to remove odors. As a result, the odor generated in the evaporator or dust attached to the evaporator is not supplied to the user, thereby improving convenience of use.

It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention as defined by the following claims .
